Threat actors are exploiting a critical command execution flaw, now tracked as CVE-2026-110447, in the Collabora Online - Built-in CODE Server app (richdocumentscode) for Nextcloud. Multiple administrator reports indicate that attacks began in mid-September, roughly a month before the formal security bulletin, the GitHub advisory, and CVE publication. CVE-2026-110447 impacts richdocumentscode versions before 26.4.303 and resides in the Nextcloud app’s mechanism for starting the bundled Collabora server. The flaw affects only the optional built-in CODE server app. Standalone Collabora Online servers, Docker and RPM/DEB installations, and Nextcloud All-in-One deployments remain unaffected, according to Collabora. The attacks involve sending a malicious request to the app’s proxy.php endpoint, triggering OS command injection.
Google announced new AI-powered defenses against scam messages and call-forwarding abuse on Android, currently rolling out to eligible devices.

Google says its existing Phone and Messages scam detection flags more than 5 million suspected scam calls and texts monthly, but the new measures are expected to catch even more threats.
